I invest only in projects whose idea can bring great success and profit, and thereby make good money on this
Aside project investment which is a good way to go also, I would have really loved to also mine, but the challenge has been with the cost associated to mining, mining has the class of people that can go for it and that is actually the rich people, and as they say that the rich keeps becoming richer and the poor getting poorer, but in my own case, even if I cannot mine because of the cost, there are other available opportunities that one can take like what you said.
Investing in project is also one way to make money, that is when you invest in solid and quality projects, and also trading too, after I have made investment, I go fully into trading too and all these ones has made me the same with someone mining also. We both get profit and we both almost make the same profit.
